Dict of Hist. of Ideas: Neo-cons sometimes close to fascism

[HereSince1628]

Although snipped pretty heavily to meet the "few paragraph" rule to avoid infringments, I think I avoided doing violence to the flow of ideas. On edit: the emphases using caps are mine.

The paragraphs of interest come from near the bottom of a long article. I included the authors outline headings to help you navigate the original...

tury conservatism has in different ways moved away
from being defensive as a result of the influence of
industrialization and capitalism...

...The conservative “intellectual” has come forward to
express the discontent felt for both the world of
bourgeois capitalism and the programs of socialism;
in his formulating new myths, forecasts, and schemes
a skeptical, sometimes even nihilistic, accent has not
been lacking. Appearing increasingly less aristocratic
or class-oriented than intellectual and elitist, this type
of conservative has attained his most widespread
influence in conjunction with MILITANT AND
INTEGRATIVE NATIONALISM ...

Neo-conservatism of this kind had its day on the
continent of Europe especially after World War I. It
was able to represent itself as a new national socialism

national movements and national dictatorships, so that
IT SOMETIMES CAME VERY CLOSE TO FASCISM . One must,
however, carefully distinguish between the “right” and
fascism. The incorporation of elements of conservative
thought in the wake of fascist movements and systems
has been so damaging for the former that it is only
with the greatest difficulty that a program of inde-
pendent political conservatism can be formulated.

1. So a couple of questions...

Are there historical/ideological links between the US Neo-Conservative movement and 20th century European movements that have the same label?

Was Leo Strauss linked to this movement while he was still in Germany in the '20's?

What is the credibility/policital affiliation of the Dictionary of the History of Ideas?
